PUMP.

Specification of Letters Patent No. 11,192, `datedkune 27, 1854.

To all whomz't may concern e Be it known that I, IRA CARTER, of Cham-h plain, in the county of Clinton and State of New York, have invented a new 'and Im-4 proved Mode `of Making Force-Pumps; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanyingdrawings and to the letters of reference marked thereon. A g

The nature of my invention consists inthe peculiar form and operation of some ofits constituent parts, with which I constructpumps to beoperated two different ways, in cluding, first, the bodyof the pump composed by 'two shells so formed that one of them envelops the other, their dimensions andappendages hereinafter described. The outside shell I call a cylinder, theiinside shell I call a core, and with the same patternsby changing `the locality of the induction valves and some other appendages, ,I construct pumps to be operated by applying the `power to a lever attached to the core, and also to be operated `by applying the power to a lever attached to the cylinder. Secondly, the `form and operation of the induc-` tion valves, and mode of placing them, and, thirdly, the Inode of oscillating by a combi`- nation of gearing whereby two cranks are brought to act upon one lever between them vertically attached to that `part ofthe pump i to be operated.`

i `Toenable others skilled `in the art to make and use `my invention I will proceed lto describe its construction and operation.

Commencing `with the body of the pump i by a core `and cylinder affixed horizontal, in

all cases when the `power is applied to either of these shells the other must be made firm 'j by means hereinaft-er described to a frame or any other foundation desired. I make a cylinder round at the ends and with flanges to bolt the heads to, and around the whole length 5j; of the circumference, `The remainder is occupied by a `hollow lug raised tapering each side, toward the center till it meets the core-shaft. The core is la tubular shaft through the center of` the cylinder. Its ends work as journals in the cylinder heads. It has a lug upon it that fills jpart of the whole cylinder, thus inclosing a vacant space in each side between the lug belonging to the core, and the lug .belonging to the cylinder.` I make a groove in the lug belonging to the cylinder for packing against the core shaft, and I make another groove directly above that in the shell of the cylin-` der and continue it down ;at the ends inthe cylinder heads to meet the. former groove, by,

a `recess around the core journals, for pack# ing also, thus stopping all leakage 'by a belt of packing `longitudinally around the lug of the core. Said lug is hollow. Its inside serves as an 4air chamber, `and its outside acts in the capacity ofphngers.

I in general construct my .pump principally of cast-iron. The cylinder requires no j nishing with the except-ion of a few bolt 4.holes and bushing the'cylinderheads for the core journals to work in. All the roundpart of the core should .be turned and made smooth thatthe packing may slide easily upon it.

I `prefer leather packing for cold water.

Where `heat meets it soft metal maybe used or cotton. The red where it is found in the accompanying drawings shows the grooves containing the packing.

The Figures` I, II, III, and IV show the mode wherethe cylinder is `made stationary and the pump operated by applying the power to a lever attached to ithe zcore. Figs. V and VI show the mode where the core fis made stationary and thepower `appliedto thecylinder. Fig. I `is an external `perspective view of the end where the cranks .are appliedtto the lever, Fig. II is an external section of the other end showing the gears to operate the cranks,` Figs. III andVare longitudinal sections `of `the .two modes `of operatingshowing the body ofwthe pump split through themiddle, Figs. IV and VI are transverse verticalsections of the two modes ofoperating also. i e

The salneletters refer to like .parts in `both cases. i i 3 A A are the cylinder heads.

B Bare friction wheels on the wrists of the cranks C C, which operate on lever D, said lever being madeufirm on the :end of the `core shaft E. i

F F are 'bevel gears `onlthejends offthe crank shafts I-I VI-I. j

Gr G are boxes attached `to :the cylinder `heads extended out like arms `for ithecrank shafts to run in. The 4cranks are made firm on the shafts at one end of the pump and operated by men' o-r by aV belt and pulley.

L is a'boX attached tothe cylinder head for driving shaft K to run in.

M'refers to the/eduction pipe.

n a n refers to the cylinder.

r0 0 o refers to the core.

Il will now proceed to conclude the description': Where the cylinder` is made startionary, I make the cylinder round at the ends.

ends, with flanges to bolt the heads to. I make both heads of one pattern with feet R R by which the pump is bolted to whatever the case may require. I make a square opening inthe shell under the lug S belonging to the cylinder, where I insert the induction valves being housed in by said lug. I make the valves hollow to do away with heft, and make them in the following form: The side that closes the port holes I make on a curve and taperin to a small round in the angle 42 and at surfaces on the l I hinge the said valves to a bar between them, in the' circle of the main shell of the cylinder and being housed in the lug belonging to the cylinder. Thereby said valves p p inclose an air chamber T, between them, it being an advantage to their operation. Another advantage in the principle of these valves'is ytheir closing the port holeson a t to.

circle section .against the water after it passes them, thereby obviate the backlash and lost suction which all pumps are subject Said valves follow each other in their motion and open and shut as the core oscillates above them. The port holes are oblong square like mortises ineach side of the lug neXt to the main shell of the cylinder. I make the shell around the opening under the valves to sag down in order to give it the. right shape to bolt the induction pipe to it. The coreo 0 0, is a tubular shaft through the center of the cylinder and has a lug upon it that fills about part of the cylinder, leaving a vacant space in each side to receive the water, which is from thence admitted into the core by a pair of valves g g and discharges out o-f one end of the core shaft into the eduction pipe M, that meets it in the cylinder head. The other end of this core shaft is closed up and extends out through the cylinder head, and has a lever attached to it by which this pump is operated. The other mode of operating where the core, is made stationary as shown by Figs. 4V and VI, I make the cylinder precisely the same shape of the former inside with .a lug S raised toward the center, but no port holes in it. .All the valves are applied to the core in this case. I make a partition in the middle of the core and divide the tube into two disconnected parts and apply a pair of valves to each part. One pair p p allows the water to pass into the cylinder, and another pair g g admits it into the `other part of the core and discharges as in the other mode of operating, making one end of the core shaft the induction pipe I and the other end of core shaft the eduction pipe M. the core shaft extend out through the cylinder heads in this case, and put a collar on each of them secured by set screws or keys. Said collars branch downward like I let both ends of legs r r, which may be bolted to a frame or platform, thereby make the core stationary. This pump can be operated by a lever attached to any part of the cylinder.

What I claim as my invention and desire to secure by Letters Patent is I l. The mode of attaching the lug herein described made tov the cylinder, and the grooves to contain the packing.

2. The form and operation of the induction valves being housed in by the lug of the cylinder inclosing an air chamber between them, and closing the port holes on a circle section against the water after it passes them, thereby obviating lost suction.

3. The form and principle of the core which maybe made a stationary part in a pump, or an operative part by changing the locality of t-he induction valves only.

4f. nd fourthly the mode of oscillating Y,
